<P><STRONG>Functional Details</STRONG>
<P>
This module prepares a specified object for one or more rotations about
a specified axis.
<P><B>Note: </B>A Transform object containing the specified transformation
matrix
is inserted at the root of the object.
This transform is applied during rendering.
<P>
Each rotation is specified by an axis-rotation parameter pair.
<TABLE CELLPADDING="3">

</TD></TR><TR VALIGN="TOP"><TD><P><B><TT><STRONG>rotation</STRONG></TT>
</B></TD><TD><P>specifies the extent of rotation (in degrees) about the

axis.
<P><B>Note: </B>Rotation is counterclockwise in a right-handed coordinate system
and relative to the origin of world-coordinate space.
</TD></TR></TABLE>
<P>
A single Rotate module can specify a maximum of 22 rotations (i.e.,
<TT><STRONG>axis&nbsp;-&nbsp;rotation</STRONG></TT> pairs).
In the user interface, the default number of corresponding tab pairs is two.
(Tabs can be added to the module icon and removed with the appropriate

<TT><STRONG>...Input Tab</STRONG></TT> options in the
<TT><STRONG>Edit</STRONG></TT> pull-down menu of
the VPE.)

<P><B>Note: </B>If you want to use the mouse to rotate the object in the Image
window, see <A HREF="usrgu040.htm#HDRROTOBJ">"Rotating the Object"</A> in <I>IBM
Visualization Data Explorer User&#39;s Guide</I>.

<P><STRONG>Components</STRONG>
<P>
All input components are propagated to the output.
